title: [Determination of the nucleotide sequence and characterization of the novel aminoglycoside phosphotransferase aphVIII gene from the Streptomyces rimosus strain].
abstract: The nucleotide sequence of a BglII-PstI DNA fragment that contains the cloned aphVIII gene from the Streptomyces rimosus P3 strain, the producer of oxytetracycline, was determined. It was established that the aph gene encodes neomycin phosphotransferase that differs by substrate specificity from neomycin phosphotransferases encoded by aph genes in producers of aminoglycoside antibiotics and clinical bacterial strains. The gene was shown to be 777 bp in length with the mean GC content equal to 67%. The amino acid sequence possesses all highly conserved regions typical for aminoglycoside phosphotransferases; however, this sequence contained several amino acid substitutions that have been detected for the first time, including those in the domain responsible for the association with antibiotics.
